patch to fix realloc bug leading to segmentation fault
Description of problem:
when using the -acpitable option to qemu-kvm, memory corruption occurs and quite often a segmentation fault. this is due to mis-use of "realloc". this has been fixed upstream.
a least impact patch is attached.
Version-Release number of selected component (if applicable):
seems to depend a bit on the machine, because sometimes realloc will return the original pointer. on two machines here, it always happens on one, never on the other.
Steps to Reproduce:
1. /usr/libexec/qemu-kvm -acpitable x /dev/null
pops up "console" window
i have attached the "least impact" fix for the bug.
